A filter is provided for beverage machines such as coffee machines. The filter material is a layer of woven or molded polymeric plastic having a mesh size of between about 52 and 70 microns. Filter material is supported by a coarse support grid which in turn is supported by a carrier.
A filter plate (1) is described on which a filter cloth (4) is disposed across the whole top side and glued or welded to the outer sides, and which is used for filtering off particles from a liquid. The plate has a large number of apertures (2), each individual aperture area being at most 2.25 cm.sup.2. The total free open area of the plate is 70-90% of the total plate area and the thickness of the plate is at least 5 mm.
A filter device adapted to separate immiscible liquids in beverages such as coffee or tea and other consumable material such as soups and gravies is so designed whereby the beverage or other consumable material passes through a special prewetted filter cloth member and the oils or other immiscible organic liquids contained in the consumable material are coalesced and retained upon the surface of the filter cloth member. The special filter cloth member is formed of synthetic fibers having a low moisture regain, provided with a multiplicity of fine interstitial openings and is napped on the upper surface.
A bacteria filter includes a pair of generally conical housing sections having confronting marginal flanges adapted to be welded together to seal the sections into an integral filter housing. The flanges have a pair of tongue-in-groove connectors to facilitate alignment of the sections during assembly and to automatically stretch a filter element between the two sections during assembly to optimize the filtering capacity of the filter. Each section of the filter device has a co-axial tubular neck extension defining an inlet and outlet of the filter device.
A vibratory separator screen which is assembled in accordance with a multi-stage tensioning method. The screen is initially mounted to an annular member, such as a ring of right angle cross-section at a level of tension which is less than a desired level. This ring is then force fit over an annular frame to increase, the level of tension on the screen to a predetermined level, this arrangement maintaining the screen at this predetermined level.
4075105 - Stackable colander and base - Owned by Bonny Products, Inc. (Hewlett, NY) [*] Notice:The portion of the term of this patent subsequent to December 6, 1991 has been disclaimed.
A colander is mounted within a stackable base adapted to rest on a surface and to support the colander above the surface. The base includes a top wall, which receives and retains the colander, and supporting legs with the colander disposed between them. These legs are shaped to permit a paired colander and base to be stacked within other paired colanders and bases.
